The Cell Cycle: Understanding Cell Division for Growth, Repair, and Asexual Reproduction

Discover the stages of cell division and the cell cycle, from interphase to cytokinesis, exploring why cells need to divide for growth, repair, and asexual reproduction. Learn about mitosis phases: Prophase, Metaphase, Anaphase, and Telophase. Witness the formation of new identical daughter cells.

Presentation Transcript

  1. Cell Division & The Cell Cycle

  2. Why do cells need to divide? • Growth • Replace worn out cells • Repair (healing) • Asexual Reproduction

  3. 1.) Interphase • Cell grows to full size & prepares to divide • DNA is COPIED!!!!! • This phase takes the longest The PARENT CELL

  4. 2a.) Mitosis- Prophase • DNA condenses to form chromosomes & they become visible (X) • Nuclear membrane breaks down intoPIECES

  5. 2b.) Mitosis- Metaphase • Chromosome line up in the middle of the cell • Chromosomes attach to the spindle fibers

  6. 2c.) Mitosis- Anaphase • The duplicated chromosome splits & the chromatids (chromosome halves) move to opposite ends of the cell • Chromatids move “AWAY” from each other

  7. 2d.) Mitosis- Telophase • 2 new IDENTICAL nuclei are formed • Cytoplasm pinches in the middle to form a waist

  8. 3.) Cytokinesis • Cell completely splits & 2 new IDENTICAL cells are formed • They are called “Daughter Cells” • “Cytokinesis = Complete” 2 DAUGHTER CELLS
